Windows services run under a user context, in general “Local System” or other system accounts.
When windows is installed for the first time, you create a default user account “Administrator” including regional setings, all the system accounts will be created using the same profile used for that “.Default” account.
That’s why using CultureInfo to change your Windows Service is not going to work.
If your System Accounts are running with undesired regional settings and you want to change that, follow these steps:
- Open ControlPanel
- Open Region and Language
- Click Administrative tab
- Click Copy Settings
- Check “Welcome screen and system accounts”
- Click Ok
